Directed by singer Nadia Larcher and pianist Andrés Beeuwsaert, a key work of rock is addressed: the album Almendra, from 1970. The concert marks the beginning of the cycle Luis Alberto Spinetta: Essential Records, dedicated to the fundamental works of Flaco. With special guests such as Ricardo Mollo and Nicolás González (Sig Ragga), and the participation of the visual artist Sol Carta, Larcher and Beeuwsaert make versions that account for the wonderful creations of Spinetta, Edelmiro Molinari, Rodolfo García and Emilio del Guercio. Almendra is performed in its original order, with new sounds and the staging is inspired by the literary and visual perspective of Luis Alberto Spinetta. The album, released on January 15, 1970, is unanimously considered one of the most inspired and original of all Argentine music.
